Concrete is a massively strong material, and its strength is a major part of why people use it. It’s used to build foundations for skyscrapers and highway bridges, to reinforce tunnels and even in home construction. When it’s mixed correctly, and poured properly, concrete can withstand significant loads without cracking or breaking apart. This is because of the concrete’s incredibly high compressive strength, which can reach 20,000 pounds per square inch (psi).
Concrete’s compressive strength is based on how much force it can withstand when it’s put under compression. Engineers use this number to determine how much concrete is needed for a project, taking a conservative approach for safety’s sake. Typically, they’ll also specify the concrete’s tensile and flexural strength.
Concrete's durability enables it to maintain its structural integrity over a lifetime, allowing buildings and infrastructure to last longer than structures made of other materials. It is a critical element of sustainable construction, since it reduces the need for maintenance and repair and prolongs the life of buildings over their entire operational lifespans, saving money and energy and reducing upfront embodied environmental impacts.
Durability is determined by a complex interaction of internal and external factors, including the water/cement ratio, hydration of cement, aggregate size distribution and curing conditions. Concrete also requires reinforcement to provide the tensile strength needed to withstand the stresses that develop in a structure.
Cement, sand and crushed stone (fine and coarse aggregate) are the primary ingredients in concrete. The ratio of these three components determines the workability of a concrete mix and the strength it achieves, with higher water-cement ratios producing weaker concrete. Concrete admixtures such as fly ash, silica fume and plasticizers can be used to adjust the water-cement ratio, while enhancing other properties such as strength and durability.
Concrete is a versatile and durable material that can be used in many ways to help build sustainable structures. Its versatility and durability help reduce the need for maintenance and repair, reducing the demand on natural resources. It is also easy to recycle. The EPA estimates that nearly a million tons of concrete are recycled each year. In addition, a significant portion of the energy that is used to produce concrete can be saved by using supplemental cementitious materials (SCMs), such as fly ash and slag cement; by using higher-strength concrete; and by improving production methods.
One way to boost a concrete’s strength is with innovative new construction technologies, like ultra-high-performance concrete (UHPC). UHPC outperforms traditional concrete in all areas of strength, from tensile and flexural strengths to compressive and flexural resilience. The result is superior strength, lower maintenance costs and a longer lifespan for any new or existing concrete project.
While the cement industry is committed to improving its sustainability, there are limits to how much it can accomplish on its own. In the past, large amounts of natural materials were used in concrete. Today, this practice has largely been replaced by concrete made with recycled aggregates, which is a more environmentally responsible solution. Additionally, concrete components are typically cast to precise specifications, minimizing the amount of waste that is produced. Concrete's durability also means that it can be used over and over again, which further minimizes the need to replace or recycle it.
Moisture levels can negatively impact the durability of concrete, resulting in phenomena such as efflorescence and moisture-induced deterioration. Proper drainage and surface treatment help mitigate moisture-related durability issues. Temperature fluctuations can also adversely affect the durability of concrete, influencing hydration rates and inducing thermal stresses. Incorporating insulation and effective temperature control methods help mitigate this issue.
